16 Undressing yourself inelegantly - which includes taking your socks off after your underwear
Nothing is more comical (or pathetic) to a woman than a man in his socks and pants. Except possibly a naked man wearing socks. If you don't understand why, just accept that it is so.
17 Expecting her to shave for you
You might like the baby smooth look around her vulva, but she's more likely to see this as a prickly route to itchy stubble. Ask her nicely if you'd like her to go smooth. If she says "no", accept that graciously.
18 Sticking a finger up her vagina before she's ready, willing and able
In general, women do like to be penetrated just as much as men like to penetrate, which, considering how much men like to stick things up there, is just as well. However, she'll only want you to do this when the time is right - i.e. when she's aroused enough to enjoy it. If you're giving her clitoris attention, there'll be a point where she might like to have a finger or two inside her. If so, be gentle, and start with one finger on her G-spot. Make sure she enjoys this before you put another one up there. Two fingers on her G-spot is probably as much as she will want. And be just as firm with your touch as she finds pleasurable. If you don't know what the G-spot is, then do some Google-ing before you get into bed.
19 Entering her without asking her first
What is it with men and these dark, wet places? Just keep in mind that she decides how far sex goes, and if she doesn't want to enjoy intercourse then don't press the point. This applies especially to any strategy that involves nudging your penis into position and then pressing forward without her consent, verbal or otherwise! Having said that, you don't always need to ask "May I enter you?" though it can be a romantic and sexy thing to do if you're looking deep into her eyes. Needless to say, that's most likely to happen in the man on top position, which, by the way, remains everyone's most popular position for sex.
20 Pecking away around her vagina with your penis if you can't find the way in
This is, by all accounts, many women's least desired sexual moment. If for any reason you can't get in, don't pretend you're in control and keep trying. Simply ask her to guide you in with her hand. That way you'll save a lot of embarrassment, not to mention time.
20 Pumping away without regard for her pleasure
When you've achieved your most desired objective, and your penis is inside her, you'll want to show a certain consideration for her pleasure. She may want hard and fast thrusting, but it's best to start slow and shallow. While you're making love, she'll most appreciate your efforts if you're masculine and strong - which is to say, if you act like you know what you're doing, you're considerate and gentle at first, and work up to firm and strong thrusts if she likes them.
21 Expecting her to make love bottom up
Yes, we all enjoy rear entry. But she may be more self-conscious of her butt, she may feel like a sex object, and she may not like the rather impersonal nature of this position. If you really want to do it, and you explain to her why you like it so much (i.e. "It's incredibly exciting to see your gorgeous bottom as we make love", rather than "I get so turned on fucking from behind") she'll probably co-operate from time to time, even if it's only on your birthday and hers.
22 Thrusting too hard
If you happen to be well-endowed, or she has a short vagina, and you thrust too hard, you may end up banging her cervix. This can make her shriek, though sadly not with sexual pleasure.
22 Coming before she's got excited or begun to enjoy sex
There aren't many men who can last long enough to really satisfy a woman who enjoys vaginal intercourse and G-spot stimulation. If you can't be bothered learning how to be a long lasting lover, then at least have the decency to keep going for a few minutes so she gets some pleasure. This isn't hard, and there are plenty of ways you can learn to extend intercourse and not come so quickly. Do some research on Google for "end premature ejaculation". See also number 26.
23 Not coming at all - or losing your erection when you put the condom on
If you're one of that rarer breed of men who has trouble coming during intercourse, may we respectfully suggest you see a sexual therapist? You can then deal with this problem, learn to come more quickly, and avoid giving her a numb vagina and an intimate knowledge of the exact shade of color you painted your bedroom ceiling. If you're one of the many men who lose their erection when the condom comes out of its foil wrapper and onto the head of your penis, it's back to Google for a search on, surprisingly enough, "losing erection when putting on a condom".
24 Asking her how it was for her
This is not the mark of a confident lover, so if you really want some feedback, phrase it thus: "Did you prefer it when I did X or Y?"
25 Not going down on her when she wants oral pleasure
Since oral sex on a woman is so pleasurable for most men, this seems unlikely. But if it's a question of the smell or taste being a bit much for you, try taking a shower or bath together before sex. If you just want her to fellate you and you simply can't be bothered to reciprocate with cunnilingus, then reading these tips isn't going to help you much anyway.
26 Failing to give her pleasure if you come quickly
Remember the motto: "Women come first!" As a man, you're probably going to lose interest in sex once you've ejaculated - at least for a while. In which case, make sure she comes through oral sex or masturbation before you enter her. That way, she gets her pleasure and so do you. (With the added bonus that it doesn't matter so much if you shoot quite quickly.) Just to enter her, thrust a few times, come, roll over and forget about her is the mark of a boorish lover, and you wouldn't want to be one of those, now would you?
27 Trying to force her head towards your cock
Let's face it: she's either willing to give your oral sex or she's not. Trying to persuade her to get her lips around your glans by edging her head towards your groin is a bit crass, to say the least. If she doesn't seem to be heading that way as things hot up, just ask her: "There's something you could do that'd give me so much pleasure....."
28 Trying to force her head further down on her cock when she's giving you oral
Yes, once again we know it feels good, but you have to be considerate about it. She's not likely to be a deep throat expert, and there's no reason why she should be, since most of the pleasure of oral sex comes from the action of her tongue on your glans. Keep your hands away from her head unless it's to gently stroke her hair, and you won't feel the temptation to encourage her to go deeper.
29 Holding her head when she goes down on you
Pretty similar to number 28, but this time, holding her head and moving it up and down on your penis is the no-no. If you think that's acceptable sexual etiquette you've been watching too many of the wrong kind of films.
30 Coming in her mouth without asking her if it's OK
The taste of semen is very much an acquired taste; unfortunately it's one that few woman ever acquire. If she doesn't like it, ask her to keep going until the last minute, then tell her when you're going to come so she can move back and finish the job with a well-lubed hand. You'll get just as much pleasure, and she won't have to gag or spit your semen out. By the way, accidentally forgetting to tell her you're going to come is not permitted.
